Conflicts: drivers/net/usb/qmi_wwan.c net/batman-adv/translation-table.c net/ipv6/route.c qmi_wwan.c resolution provided by Bjørn Mork. batman-adv conflict is dealing merely with the changes of global function names to have a proper subsystem prefix. ipv6's route.c conflict is merely two side-by-side additions of network namespace methods.
